Abstract

A catheter pump assembly comprises a pump including an impeller assembly and a catheter body disposed proximal to and supporting the pump. The catheter body includes relatively hard sections adjacent to a relatively softer middle section such that the middle section is configured to contact a wall of an aorta of a patient.
